Twitter managers were initially told to cut 25 percent of the work force, reports said. This rose to half, and then 7,500 staff, it was later claimed.

It comes as Musk tweeted that Twitter will do "a lot of dumb things" in the coming months, referring to its tech ability rather than top brass decisions.

His full tweet read: "Please note that Twitter will do lots of dumb things in coming months. We will keep what works & change what doesn't."
